Abstract

The invention discloses an intermediate support structure for improving rigidity and shock absorption, which comprises an upper bracket, a lower bracket, a rubber pendant and a bearing. The pendant is ring-shaped, and the outer ring surface of the rubber pendant is clamped in the circular space formed by the fastening of the upper bracket and the lower bracket. The inner ring surface of the rubber pendant is provided with a first groove, The bearing is assembled and arranged in the first groove, and protruding ribs are uniformly arranged between the inner ring surface and the outer ring surface of the rubber pendant. The intermediate support structure for lifting stiffness and shock absorption of the present invention avoids the aggravation of the vibration of the rear axle, transmission system, and vehicle body due to the vibration of the transmission shaft and the intermediate support structure, and avoids coupling with the road surface excitation, which will cause vibration to the entire vehicle at low and high speeds. The noise has been significantly improved to achieve the purpose of reducing vibration and noise.

Description

technical field [0001] The invention relates to a supporting structure of a transmission shaft, in particular to an intermediate supporting structure for improving rigidity and shock absorption. Background technique [0002] For front-rear drive vehicles, in order to reduce the vibration of the transmission shaft, avoid the vibration of the rear axle, transmission system, and vehicle body due to the vibration of the transmission shaft and the intermediate support, and avoid coupling with the road surface excitation to achieve the purpose of reducing vibration and noise. It is often necessary to increase the radial stiffness of the intermediate support and the rigid body mode of the transmission shaft. [0003] For the current intermediate support structure, its rigidity is low. Stiffness can only be increased by increasing the hardness of the rubber. However, after the hardness is improved, it is difficult to assemble the intermediate support assembly, and it is difficult ...
